The movement designates black women who wear afro-textured hair in its natural, coiled or curly state (as well as those who do not chemically straighten their hair but may still choose to wear it straight). The word "nappy" has been subjected to denigration since the Atlantic slave trade. Thereafter, some Afrodescendants have positively taken the word back, considered in francophone countries as a backronym made up of "natural" and "happy."[3][7][8][9]

These women, called "nappy girls" or "nappies," give "relaxing" up and let their hair grow in its natural texture. Their hairstyles can be simple or more sophisticated, by the adoption of hair twists, braids or even locks.[3][10] Not everyone who wears their natural hair chooses to forgo all (non-chemical) forms of straightening or styling. Additionally, "being natural" does not necessarily indicate a strict adherence to any particular type of product or styling regimen; nor should it be tied exclusively with certain social or political beliefs. Women (and men) choose, or are forced into, being natural for a wide variety of reasons. Some may even not like the term "nappy/nappies."

Around 2005 an underground documentary film hit the independent film circuit called "My Nappy ROOTS: A Journey through Black Hairitage". The highly acclaimed film won multiple awards and played on the college circuit. With years of research, the film historically looked at the word "Nappy"; "My Nappy ROOTS" chronicled over 400 years (and 200 hours of footage) of Afro hair culture starting in Africa through the middle passage, reconstruction the creation of the Black hair industry to current day 2008. It became the definitive film on the history, culture, and economics on Black hair. The urban story postulated the word 'Nappy' came from the cotton plant, the small cotton ball inside the plant was called a 'nap'. The word nappy was born because it resembled the texture of unkempt Afro-textured hair. In an effort to be more acceptable socially, it was more desirable to have straight hair like the dominant culture. Once mixed race children were born, Black people internalized that 'Nappy' hair was 'bad' unacceptable hair. This historic film has never been publicly released. It wasn't until the public lawsuit in 2009 with Chris Rock's "Good Hair" that the concept of Nappy (and use of chemicals) was publicized worldwide. The world understood the concept of "good and bad hair" or "political hair" commonly referred to in the African American community. My Nappy ROOTS began screening to sold-out audiences worldwide. International screenings of the film, MNR and the organization called International Black Hairitage and the internet helped to introduce the word "Nappy" to Afro cultures that did not know the word or its meaning. From the US to UK, France, and Africa, some black women have realized that their nappy hair can be beautiful to them. This calls into question the subconscious internalized association nappy = ugly; They stop therefore to comply with the dominant aesthetic ideal of beautiful hair = smooth hair. Through their hair, the nappies thus reconcile with their original African heritage.[3][11][12]

This return to naturalness, at the organic era,[13][14] has been encouraged by the awareness of the harmful effects of relaxers on the scalp: Itches, red patches, burns, broken hairs or worse: alopecia (hair loss). However, among black women, 98% have had their hair straightened at least once in their lives, and relaxers have represented no less than 70% of the cosmetic purchases carried out by the population. In the 1980s-1990s, hair straightening was mainstreamed.[8]

Sooner, in the 1970s-1980s, the ′Jheri curl′, another technique to loosening the nappy hair, became fashionable in the African American community, popularized especially by some celebrities such as Michael Jackson, seen in the music video for his song Thriller.

During these same years, a new hairstyle appeared too: dreadlocks (naturally matted hair locks), popularized by Bob Marley and more generally by reggae music and the Rastafarian movement. This hairstyle can be a mark of social and spiritual distinctions: "The adoption of long or very atypical hair [can reflect] rebellion or a refusal of the dominant values."[9][15]

During the Atlantic slave trade, the conditions of servitude did not allow to take care of one's hair, which was subjected to denigration by the master: "Nappy′" became a pejorative term.[18][19]

The deportation of millions of Africans get them separated from their originally aesthetic activities regarding hair care.[17]

In the ancestral traditions, hairdressing was "an activity during which the genealogies' history and many other cultural features were taught to children. Every African hairdressing was codified according to the ethnic group and by status."[6]

It is the loss of this instrument [the African comb], all the more valuable that it is essential to the nappy hair care, which was going to dissociate Black people from the nature of their own hair, considered therefore as "difficult to comb".... The African was snatched from his comb when he was snatched from his native land and thus taken away from an irreplaceable cultural symbol, legacy, and accessory from his beauty culture.

These websites have expanded the natural hair movement around the world so as to highlight the beauty of natural African hair.[3][4][17]

Each woman has her own reasons to retrieve her authenticity; some of them want to preserve their hair against aggressive hair styling methods (weaves too tight) or harmful straightening chemical products; for others, they simply prefer nappy hair aesthetically or in spite of the pressure from the dominant aesthetics.[6][7][8][11]

With the popularity of "going natural", hair care suppliers have seen a rapid decrease in the purchase of relaxers, the harsh chemical hair straightener. An industry that was once worth an estimated $774 million, relaxer sales have gone down 26% over the last five years, 2013 numbers report.[82] Sales are estimated to decrease to 45% by 2019.[82]

Women who wear their hair natural are now spending more money on products that will achieve the best result for their hair, and hair care suppliers and markets are taking note. Black consumers represent a lucrative market for hair care suppliers, so the brands now have to adjust for the new hair movement.[82] Brands have greatly lowered their production of relaxers and instead now produce more natural-friendly products. In choosing what products to consume, black consumers rely heavily on social media to gauge results from others who have gone natural. They have done this by the use of YouTube videos as tutorials on how to use products efficiently and create reviews for potential consumers to watch. Popular brands and products include Shea Moisture, Deva Curl, and Carol's Daughter.[83]

Many black women have faced pushback from wearing their hair in naturally curly styles or other non-straight, protective styles. At the 2015 Oscars ceremony, Fashion Police star Guliana Rancic commented that the hair of teen star Zendaya Coleman—who chose to wear locs on the red carpet—must have smelled of “patchouli oil or weed.” This is in contrast to Rancic praising the look as “edgy” when worn by Kylie Jenner.[84][85]

Many women have found that they are treated unjustly simply because of the natural way their hair grows. Natural hair can be deemed as “unprofessional,” turning it into a fireable offense. For example, a 12-year-old student at a Florida Christian school with natural hair "was given one week to decide whether to cut her hair or leave the academy that she has attended since third grade" after she complained to school officials about being bullied by other students.[86] In March 2014, the Department of Defense issued a set of guidelines that banned all afros, dreadlocks, braids, and twists that were greater than ¼” in diameter. Guideline such as these clearly disproportionately affect and target those of African descent.[87] They later rolled back the guidelines that same year in August, allowing two-strand twists, the Army increased the size of permissible braids, and the Army removed the word "unkempt" from their guidelines.[88] In April 2016, a female Toronto Zara employee was reprimanded for wearing her hair in a braided hairstyle, which resulted in her filing a complaint with the Ontario Human Rights Commission.[89]

Some nappies, dubbed "nappex" (nappies considered extremists), have become radicalized and claimed that hair straightening is a mark of self-denial. These guilt-creating considerations are denounced by India Arie and her song I Am Not My Hair.[17]

shrinkage: Because Afro-textured hair is typically coiled in style, in its natural state it appears shorter than it would straightened.

nappex: Nappies considered extremists.

co-wash: Washing one's hair with conditioner instead of shampoo.

wash and go: Simply means you wash your hair and go on about your day. This means there is no drying or styling involved and the application of product is minimal (usually a moisturizer or anti-frizz serum). The wash and go is also sometimes referred to as the "shake and go" which further emphasizes the lack of actual styling involved.

braids : Hairstyle where hair is braided with extensions or with natural hair.
